摘要
该研究结合钢板和预应力碳纤维板两种加固方法,钢板可以为预应力碳纤维板提供可靠的锚固,减少碳纤维板因为锚固端滑移和变形引起的预应力损失,同时钢板又可以作为新浇混凝土的模板。这种方法是一个主动受力的过程,在加固完成之后即可提供承载力。采用ABAQUS建立有限元模型,结果表明,加固后混凝土梁最大等效应力提高了63.25%,延性有明显增加。
Two reinforcement methods are combined with steel plate and prestressed CFRP in this paper,that steel plate can provide reliable anchorage for prestressed CFRP,which also can reduce prestress loss caused by the slip and deformation of the anchorage end of CFRP,and it works as model for the new concrete at the same time.This method is an active force process,which can provide the bearing capacity after the reinforcement.The result shows it can increase the maximum equivalent stress by 63.25%,and the ductility increased significantly through a finite element model established by ABAQUS.
